1 System Description
1.1 Introduction
The digital system comprises of a Transmitter and a Receiver, whose output RF
frequency is in the Band 1.9GHz to 2.9GHz. The RF band is approximately 300MHz.
Transmitter is comprised of a MPEG2 Video Encoder which will take composite
Video and digitize this and compressed, the output transport stream [DVB-TS] is then
converted to DVB-ASI, which is then Modulated with COFDM (or any other digital
modulators). The COFDM modulator is compliant to DVB-T non-hierarchical modes.
This modulated signal is then converted to the appropriate with an IF of 480MHz thus
providing the means to tune over a band at the RF signal.
Receiver will down convert from the RF signal to an IF of 480MHz. This IF is then
demodulated providing a DVB-TS. This data stream is then MPEG2 Video Decoded
and provided as analogue Video output, together with the Audio channels.

1.5.1 Introduction
The product is a simplex digital radio. The following sections describe the TX system, RX
system, followed by sub-system components. Please reference the accompanying block
diagrams for clarification.
We will follow the typical end-to-end progression of a radio system starting with the TX baseband
inputs, to the COFDM modulator, followed by the upconversion process and the power amplifier.
We then proceed to the RX preamplifier input, the down conversion process, followed by the
COFDM demodulator and baseband outputs.

All modules (excluding the Front Panel and Power Amplifier) are interconnected via the
backplane that traverses the entire width of the unit. The backplane contains the various
communication buses as well as the PA (Power Amplifier) control and redundant transfer
circuitry. See Figure 5 below for locations of the Backplane and the Power Amplifier. The power
supply levels and status are monitored on the backplane and the NMS/CPU card processes the
data.
Figure 5: Location of the EXPEDIO Backplane and Power Amplifier
The NMS/CPU card incorporates microprocessor and FPGA logic to configure and monitor the
overall operation of the system via front panel controls, LCD screen menus, status LEDs and the
bar graph display. Module settings are loaded into the installed cards and power-up default
settings are stored in non-volatile memory. LCD screen menu software is uploaded into memory,

Figure 8: RF Upconverter Block Diagram
The IF output carrier of the IF Upconverter daughter card is fed to the transmit portion of the RF
Module via an external (rear panel) semi-rigid SMA cable. This module performs the necessary
upconversion to the RF carrier. There is an on-board CPU for independent control of the critical
RF parameters of the system.
Since this is a linear RF processing chain, an automatic leveling control loop (ALC) is
implemented here to maintain maximum available power output (and therefore maximum system
gain). The ALC monitors the PA forward power (FWD) output sample, and controls the up
converter gain per an algorithm programmed in the CPU. The ALC also controls the power-up
RF conditions of the transmitter output.
1.5.4 Power Amplifier (PA)
The Power Amplifier (PA) is a separate module that is mounted to a heat sink and is fan-cooled
for reliable operation. The PA is a design for maximum linearity in an amplitude modulation-based
system.

The receiver handles the traditional RF to UHF conversion from the carrier to 480 MHz.
Considerations are given to image rejection, intermodulation performance, dynamic range, agility,
and survivability. A separate AGC loop was assigned to the RF front end to prevent
intermodulation and saturation problems associated with reception of high level undesirable
interfering RF signals resulting from RF bandwidth that is much wider than the IF bandwidth.

2-1 Status Monitor Program
602-13729-01 Rev B Expedio Digital Electronic News Gathering Radio
2 Status Monitor Program
2.1 Description
The Expedio Status Monitor Program is a application that allows you to monitor the status of the
Expedio unit from any Windows-based PC.
2.2 Software Installation
1. Power OFF the Expedio unit and the PC.
2. Connect the serial cable (RS-232) from the PC to the Expedio unit.
3. Turn the Expedio power ON, and then turn the PC power ON.
4. Run the Expedio Self-Extracting Executable from the Expedio CD.
To launch Expedio, double click the Expedio icon on your PC desktop. The first time you run the
Expedio Status Monitor Program, the Communications Settings window appears.
To begin communicating with the Expedio unit, the Communications Settings must be properly
configured.
• In the Comm Port field, select the Comm Port to which the Serial Cable to the Expedio
unit is connected.
• In the Baud Rate field, select the Baud Rate as configured on the Expedio unit. For more
information about configuring the baud rate, see the section of this manual regarding
hardware setup.
• Optional: Check Status on Startup automatically causes the Status Monitor Program to
begin monitoring the Expedio unit each time the program is launched.
Click OK to accept these communication settings.

Status Monitor Program 2-2
602-13729-01 Rev B Expedio Digital Electronic News Gathering Radio
2.3 Using the Status Monitor Program
2.3.1 Start/Stop Status Check
Status Checking can be started in either of two methods:
• Automatically: Select Check Status on Startup in the Communication Settings. With
this selection, every time program is launched, it first reads the current settings from the
Expedio unit, then starts status checking.
• Manually, by
Upon launching the Status Monitor Program, the main screen appears, as pictured below. (Note
that in the example below, the Status Monitor is not currently communicating with the Expedio
unit, thus there are no or zero values in some of the fields.)
To begin monitoring the status of the Expedio unit, click Start Status Check. A progress
bar appears, indicating that the PC is attempting to connect to the Expedio unit. The amount of

2-3 Status Monitor Program
602-13729-01 Rev B Expedio Digital Electronic News Gathering Radio
time required to make a connection and retrieve data depends upon factors such as the speed of
the connection and the quantity of data.
Once the connection is made, Expedio continues to send data until you click Stop Status
Check.
The Status area of the screen displays information that received from the Expedio unit. During
monitoring, the Error Statistics continue to update anytime a change occurs on the Expedio unit
itself.
The communication link between the PC and the Expedio unit processes only one command at a
time; therefore, other features that involve communicating with the Expedio unit cannot be
performed while Status Checking is started.
2.3.2 Expedio Unit Data
The upper portion of the Status area displays information about the unit. Except for PVR, this
information is static, that is, it will not change while you are monitoring the unit.

Status Monitor Program 2-4
602-13729-01 Rev B Expedio Digital Electronic News Gathering Radio
Decoder Indicates the operating mode of the unit:
GREEN = decoder
RED = encoder
NO COLOR (background) = Unknown
PVR Indicates the PVR status:
GREEN = Valid
RED = Invalid
NO COLOR (background) = Unknown, only occurs before status is
obtained or during reset.
CPU Version The version of firmware.
FPGA Version The version number of the unit’s operating system.
Updates to the CPU Version or the FPGA Version can only be performed under the guidance of
Moseley Technical Support.
Read from Board returns status information (excluding PVR) without starting Status Check.
2.3.3 Error Statistics
The lower portion of the Status area displays Error Statistics. This is live data that the system
updates as changes occur on the unit. The represented values include:
• Time Gives the elapsed time since Status Checking started.
• TPS GREEN = Valid
RED = Invalid
NO COLOR (background) = Unknown
• Total TPS Number of invalid TPS checks since Status Checking started.
• RS Errors
• BER
• Signal Strength
• MER
The Reset Totals button returns a field values to zero. The system then updates the fields with
the current values.
